TL;DR
In-house value-added CNC machining services such as assembly and pressure testing let OEMs buy ready-to-install, fully tested components from a single partner. That means fewer suppliers to manage, cleaner process flow, shorter lead times, tighter quality and traceability, and smoother launches. If your current CNC machining partner only ships bare parts, it may be time to reassess whether they’re really supporting your program goals.
